i SCHvLZE teasers aries .Qrsmvmara e19- To all whom it mayconcernk Be it known that we, LEON F. SoHULzE and ROBERT SoHULzE, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain ,new and useful Improvements in Metal-forking Machines,of which 7 the following is a specification.

V -This invention relates to improvements in metal working machines generally-and it particularly refers to the tool support in such machines, and it forms a division of our copendingapplication, Serial No. 468,280,

filed December 19, 1908, for metal working V v 7 through the tool support and through the machine.

More specifically the invention relates to a metal working machine comprising a head having a plurality of stock spindlesand a tool support slidably mounted on the frame having a plurality of faces for receiving metal working tools, one of the faces form- 7 ing the base for supporting the tool support. The invention may be further briefly sum marized as consisting, in the construction and combination of parts hereinafter set' forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a side elevation of a portion of ametal working machine showing our device applied; Fig. 2 IS a front elevation taken upon the line 22 of Fig. 1; and Fig. 3 is a perspec tive view of the tool support itself.

In carrying out the invention any preferred form and construction of parts may be employed so long as they possess the necessary characteristics, but we have shown one form in the drawings which is highly effective in operation, and in such embodiment 1 represents the frame of the machine which is provided with a suitable stock spindle supporting member 2 adapted to receive a spindle head 3 adapted to be rotated in-' .termittently as is common in machines of this type, no mechanism for performing this function being shown since the same is considered to be unnecessary. This head carries a plurality of stock spindles, in which are mounted suitable pieces of stock5. The frame is also provided with a suitable guideway 6 upon which is mounted the tool support comprising the supporting portion 7 preferably formed integral witha multisupport.

faced tool support member 8. Each one of the faces is provided with a T-shapedslot 9 for-receiving'the suitable tools which may be of any form, such as for example a cut ting offtool 10, a boring tool 11 and 'suitable threading tools, which are represented at 12. The supporting portion 7 is provided wlth a recess 13 in its front: face.' Axially October extending through this supporting portion 1 is an opening for receiving a suitable rod 14 which forms a stop for determining the length of stock fed, this rod being held in any adjusted position by a check nut 15.

A suitable driving shaft 16 extends spindle head 3 and drives all the parts by any suitable mechanism, not shown. Supported in the main frame in any suitable manner is a'cam shaft 17 which carriesa V p ca m drum 18 provided with earns 19 and 20 engaging a roller 2l.mounted on a pin 22 shown in dotted lines'in Fig. 1' and secured in the supporting portion 7 of the tool sup port." The cams and this cam drum 18 serve to move the tool support backward and forward with respect to the work. Having described our invention, we
